Workers at the Fukushima Daiichi nuclear power plant in Japan found another water leak in the Unit 3 reactor building on Jan. 18.
According to Enformable, workers with Tokyo Electric Power Co. were operating a remote-controlled robot to remove debris from Unit 3 when they discovered a stream of water running through the building before going down a drain. The robot sampled the water and found it has 24 million becquerels per liter of radioactive materials including strontium, Cesium 134 and Cesium 137.
The article said the water is coming from a room that houses the main steam isolation valve, which could indicate that the valve was either damaged during the March 2011 earthquake and tsunami or that it did not close during the nuclear accident.
